Read Genesis 31:52 Using Other Translations
This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm.
This heap is a witness, and the pillar is a witness, that I will not pass over this heap to you, and you will not pass over this heap and this pillar to me, to do harm.
They stand between us as witnesses of our vows. I will never pass this pile of stones to harm you, and you must never pass these stones or this monument to harm me.
